Two wires are fixed on a sonometer wire. Their tensions are in the ratio 8:1, the lengths in the ratio 36:35, the diameters in the ratio 4:1 and the densities in the ratio 1:2. Find the frequency of the beats (in Hz) produced if the note of the higher pitch has frequency of 360 Hz.
For the two wires, we have
…………….(i)
According to the given problem
Substituting these values in Eq. (1)
…………(ii)
lt is clear from Eq. (ii) that, has higher pitch so, n2 = 360
Now
Thus beat frequency is given as
